Have you tried booting with the [Shift] key held down to boot into

you get to the login screen.
If it still does not work, disconnect all external peripheral cables
and the AC power cord. Open the side door, remove the door and thermal
shield. Look inside, down below the memory slots about one inch up
along the bottom edge of the main logic board, just in front of the
processor intake fans, where you will see the SMU reset switch. It is
a round grey or white momentary contact switch set in a square metal
"can", much like the PRAM switches in older G3 and G4 desktop systems.
Press the SMU switch once, and once only, releasing it immediately.
Wait at least ten seconds before closing the system up, re-connecting
the external peripheral cables and the AC power cable. Try to start
the system from the OS install DVD, and reset the system password.
If that doesn't work, check and, if necessary, change the PRAM
battery. Try booting with the [Command] + [Option] + [P] +[R] keys
held down until you reach the open firmware prompt. Try the usual
NVRAM reset commands, press [Enter/Return] key after each command:
reset-nvram [Enter]
set defaults [Enter]
reset-all [Enter]
The system should restart. Hold down the [C] key as it boots to boot
to the OS install DVD. Try and change the password. If successful, see
if you can log in. As someone else suggested, be sure you are using a
wired keyboard so the keyboard will be recognized and functional when
you reach the Login prompt.
If none of the above works, boot from the ASD CD and run all the
system tests.
No, I've not tried the "Shift key", though I doubt this will respond to
any key combination. I think there's a greater problem that's keeping it
from responding to input keys during boot-up. Once it's booted, I can
see the key input. Of course, that was when it booted to the login
screen. Now it does not, though it chimes/bongs. Nothing shows up on screen.
Can someone please help as to where I can find download the ASD. I doubt
that it will work, as I think it simply won't boot off the optical
drive. But it will be nice to have, once the major issue of it not
responding to key input during boot-up is solved.
